Autapomorphies of Caribaetis.

...

Characters of Caribaetis of unclear phylogenetic status.

() Hind wing of the "Centroptilum-type": relatively narrow and long, with long hooked costal projection (see Index of characters [2.2.60]). Probably plesiomorphy [see Turbanoculata (10)].

() Larval antennae bases are not turned together, frons between them does not form a keel (unlike Fallceon and some other taxa – see Index of characters [1.1.3]).

() Larval claw [see Baetungulata (1)] bears a large seta on posterior-inner side (see Index of characters [1.2.24]).

() Larval abdominal terga with scales in operculate sockets [see Turbanoculata (12)] (see Index of characters [1.3.4]).

Plesiomorphies of Caribaetis.

In mature larva ready to moult to subimago, buds of subimaginal gonostyli are folded under larval cuticle by the "Nigrobaetis-type": 2^nd segment of gonostylus is directed posteriorly and curved by its convexity medially and by apex laterally [see Baetovectata (3)] (see Index of characters [2.3.9]).

Larval paracercus is developed.

Size. Fore wing length 3–6 mm (see Tetramerotarsata).

Distribution. Cuba.

Comment. Lugo-Ortiz & McCafferty & Waltz 1994 suggested to unite Caribaetis with Fallceon in one taxon of genus rank, but have not suggested any apomorphic or unique characters for this taxon. Later (Lugo-Ortiz & McCafferty 1996) they united several genera into a "Baetodes complex" which is characterized only by presence of a seta on posterior side of claw, ignoring the fact that such seta is present in Caribaetis, but absent in Fallceon.
